In your ini file, the P value for each axis/joint is set at 0, how did that happen?
The value should be 1000 for stepper systems with the servo period set at 1000000

Hey first of all thank you all for your awesome work!!
I have the same setup (I think) (www.aliexpress.com/item/1005006913304675...n.112.45bb1802PVhuo5)
And yes I can also hear the whining sound while the drives are active.
@Sandro would you be willing to share your whole config? I'm still very new to the whole config thing and the more files I have to compare to each other the faster I can learn.

Adding a progress bar

You can set it up similar to Qtdragon by adapting this code:
    STATUS.connect('progress', lambda w,p,t: self.updateProgress(p,t))

    def updateProgress(self, p,text):
        if p <0:
            self.w.progressBar.setValue(0)
            self.w.progressBar.setFormat(_translate("HandlerClass",'PROGRESS'))
        else:
            self.w.progressBar.setValue(p)
            self.w.progressBar.setFormat('{}: {}%'.format(text, p))

    def percent_loaded_changed(self, fraction):
        if fraction <0:
            self.w.progressBar.setValue(0)
            self.w.progressBar.setFormat(_translate("HandlerClass",'PROGRESS'))
        else:
            self.w.progressBar.setValue(fraction)
            txt = _translate("HandlerClass","LOADING")
            self.w.progressBar.setFormat('{}: {}%'.format(txt, fraction))

    def percent_done_changed(self, fraction):
        self.w.progressBar.setValue(fraction)
        if fraction <0:
            self.w.progressBar.setValue(0)
            self.w.progressBar.setFormat(_translate("HandlerClass",'PROGRESS'))
        else:
            txt = _translate("HandlerClass","COMPLETE")
            self.w.progressBar.setFormat('{}: {}%'.format(txt, fraction))

In Designer, you must set signals from gcode_viewer and gcodegraphics to call percent_donw_changed and percent_loaded_changed.

Configuration for Lathe Tool on 7i95t boards

Category: AXIS

Hi
I was wondering if anyone can help configure 7i95t configs for VFD on my lathe machine (Current configs attached). The axis work fine but the machine is giving horrible threads as spindle RPMs and Z axis are not in sync. (Maybe due to some kind of software filter perhaps).
Also the encoder is a 1000 line ppr encoder. Therefore, the 4000 in encoder scale. 
If possible, kindly share the 7i95t configs with scale, filters etc. commands so that the bounce factor in RPM feedback for the spindle are removed. 

Have checked all the cables and they are fine!

RPi4 Mesa install: No 7C81 board found

Category: Installing LinuxCNC

I have connected pi 4(powered by PI OS) with Mesa7c81 using idc26 cable and followed the instructions given in the following video

BUT when i write the command sudo mesaflash --device 7c81 --addr /dev/spidev0.0 --spi --fix-boot-block --wirte 7c81_5abobx3d.bit
I get the following error Unable to set bpw32 , falllback to bpw8
Unexpected cookie at 0100..0110:
00000000 00000000 00000000
No 7c81 board found
NOTE: i have already checked that spi communication is working using the ls /dev/spidev* command
Do you know how to correct this error? Your valuable suggestion will be highly appreciated.

I have a RPI 5 that will not install from the LinuxCNC 2.9.2 Raspberry Pi 5 OS based on Debian Bookworm i mage.
The RPI 5 is only the 2GB version. Would this be the problem?
THis RPI 5 works ok from the nomal Raspberry PI imager program

hi,
My machine has issue about following error keep rising during Gcode execution. Jogging 3 axis simultaneously at high speed ( 9m/min) for extensive time is ok. Reducing  the speed and accel to 3m/min  and lengthening timing pulse still doesn't fix the issue.
below are my hal and ini

Probe Basic Lathe - Konfiguration von Axis übernehmen

Category: QtPyVCP

Hallo Gemeinde,
ich habe fast alles an Einstellungen für meine Drehmaschine mit der Oberfläche "Axis" abgeschlossen und denke nun so langsam daran, dass Ganze in die "Probe Basic Lathe Oberfläche" zu übernehmen.

Wie gehe ich da am besten vor und worauf muss ich achten?

Tipps und Ratschläge?

"Probe Basic Lathe" ist bereits auf LinuxCNC 2.9 installiert und funktioniert auch in seiner Grundkonfiguration (startet ohne Fehlermeldung).

Danke und Gruß
Olli

At present, I have built a xyz-ac machine tool and used RTCP function, which can work in both simulation and real lathe. I referred to the official 'xyzbc-trt-kins (switchkins)' example

What do you really get for a $350 desk top engraver ?

Category: Show Your Stuff

i went back and paused that one video to take a closer look at what is going on inside the software. i think i found my adjustment needed.

the setting from the factory is 50% of the holding current. it's under closed loop holding current and has a set range of 0 to 100 % so you should be able to increase that. one thing i did notice after running the machine for 3 or 4 hours was how cool the motors were. i figured that they would has least be warm to the touch. the fact that they were still room temp still had me surprised. now i know why.

if i were to running things in open loop mode i think i would see they are getting at least warm.

i think the 50% setting is causing the correction to to kick in constantly and creates an oscillation. i think in an ideal situation they should never have to compensate so you have smooth motion but have a little extra in case you do need it.

i really do think that is my chatter problem. since i did not get in there i only have 50% because of the factory setting. i will have to find one of those cables and confirm this for sure.

Problem mit Servo und Glasmaßstab

So, bin nochmal alles Schritt für Schritt durch und bin dann auf MAX_OUTPUT gestoßen.
In einer Anleitung hatte ich gefunden, dass das Ziel wohl 10 sein soll, allerdings ist diese Anleitung auch schon relativ alt gewesen, in anderen Konfigurationen war der Wert auch wesentlich höher, also habe ich diesen Wert auch erhöht und siehe da, es funktioniert, läuft sauber einen G0 Loop durch ohne auszusteigen 
File Attachment:


Wieder ein Problem von der ToDo-Liste gelöst.

Allerdings kommen noch weitere Fragen zu anderen Problemen, womit ich bald nerven werde 
File Attachment:

Dafür aber eigene Threads damit diese später besser gefunden werden, falls jemand das gleiche oder ein ähnliches Problem hat.

Danke für eure Hilfe
